Integral field spectroscopy and radio interferometry are very powerful tools for studying the interplay between AGN and star formation (SF) in galaxies. We introduce a sample of SDSS galaxies with selection criteria designed to maximize our chances of catching both processes in action. The galaxies are post-starburst, potentially contain radio AGN, and are allowed, but not required, to have ongoing star formation. The resulting sample includes objects classified as traditional post-starbursts and ones that would have been classified as Seyferts based on their emission line properties alone. The systems span a range of merger phases from initial interaction to fully merged, providing snapshots throughout the entire sequence. We are compiling a multi-wavelength data set, including spatially resolved optical spectra from IFUs on WIYN and continuum radio maps from the VLA and GMRT. Here we present initial results on J0754+1648, an interacting system with a post-starburst region near a radio AGN surrounded by highly ionized gas. This object may be an example of SF truncated by AGN feedback.
